I tend to use Panera Bread for two main purposes: a convenient alternative to more conventional coffee shops when I'm looking for a place to park my laptop with bottomless coffee, and a go-to place for reliable good food and good wi-fi when I'm on the road. I don't go deep on their menu but have historically liked their coffee (BIG fan of customer refillable coffee) and baked goods. So there are a few things that I need to work well in Panera: plenty of electrical outlets where I can plug in my laptop or recharge my phone, clean tables near those outlets, and fresh coffee.
For some reason, this Panera fails on the first two of those conditions. The dining room is a bit smaller than a typical PBC store, and there aren't many outlets available. I've also found that they seem to be less diligent on wiping the tables than the other Madison location that I frequent. The food is good (solid - standard Panera) and the staff seem friendly and helpful. It's just not the same easy, effortless experience that I've come to expect of Panera. As a result, I don't use this location as much.
